JAVA：如何解析日志文件直到找到特定行，就像 linux 中的尾部命令一样？

Question

I want to parse the log file till specific line is found in the log file like a tail command.

I am using bufferreader and want to do something like this-

Code-

      BufferedReader br = new BufferedReader(new 
       FileReader("/file1.txt"));
       String line;
       boolean keepReading = true;
       while (br.readLine()!= null) {

         line= br.readLine();
         if(line.equals("string found"))
          {
                break;
          }
         else
           {
              //some stuff
           }}

I just want to wait for particular string, till then I just want to continue the loop but the condition is, may be the specific string is yet to come and I want to wait for it?

Answer 1

String comparisons should be done with the equals(String) method. Strings are immutable objects, meaning each string is a separate object. The equals(String) method compares the content of the strings.

Answer 2

In Java you check string equality by:

if(line.equals("string found")){
}
